8 Claims. l(Cl. `191-`45) My invention relates to trolley `controlling means for toy electric railway street cars, commonly known as trolley'cars, and-it is an 'object of the same to provide improved means whereby the driving means for the car will change automatically from an overhead system toanunderground system andA vice versa, with means to insure that the trolleyV will engage its wire with safety and certainty. -2

Another object of thev invention is to provide trolley controlling means, particularly adapted for use ina system of the kind referred to, in which the trolley will be moved through a wide arc by a small movement of its controlling means,

and will be accurately heldagainst rattling or 'f from the annexed drawingswhich-are made av part of this application and inwhich similar ref'- erence characters indicate similar parts.

Referring to thevdrawings: v f Fig. 1 is a side elevation of parts of a controlling means, with .parts injsection, v Fig. 2, a top plan of parts showninFig. 1,

Fig. 3, a vertical section of partsshown in Fig. 1, f

Fig. 4, a side elevation of part of a toy street car system, showing the car operating by means of a trolley and also operated by an underneath system, 4

Fig. 5, a top plan of parts shown in Fig. 4, Fig. 6, a detail of parts shown in Figs. 4 and 5, Fig. 7, an elevation, partly in section, of a car trolley y with a modied trolley controlling system,

Fig. 8, a partial top plan of the trolley car of Fig. '7, and

Fig. 9, a horizontal section of part of the car of Fig. 7.

In the drawings, the trolley and its operating mechanism include a rod 80 extending up through the iloor of the car and provided at its lower end with a roller 8| in a `yoke 82, held down yieldably by means of a spring 83 surrounding the rod and bearing against a collar 84 on the rod and also against the upper end of the yoke. At its upper end the rod 80 is pivoted at 86 to a bent lever 81 pivoted at 88 to a Xed upper part of the car. At its rear end the bent lever 81 is pivotally connected atv 89 to the trolley pole proper 90. This pole has a natfaced block 9| at its forward end adaptedto rest on a xed part 9| of the car when the pole is lowered, said block having a rocking and sliding movement upon the rear end of the frame portion 9| to bring it into theposition shown in dotted lines in Fig. 1.

A spring 92 connected to a pini-,93 onv the pole and to a fixed pin 94 tends to raise the trolley pole to bring the trolley 95 into operative position, in which it remains during normalpperation of the car. A` portion of an insulated third rail is shown at 96 in Fig. 5. The third rail may be at the middle ofthe track, or at one side thereof, as subway cars. When the ycar reaches such a third rail the roller '8| rides up on it, forcing the rod upward, and oscillating the lever 81 so as to `'causeiits pivotal connection with the trolley pole to bring vthe pole down into the position? illustrated in'Fig. 1.

Such operation of the'car and the trolleypole is indicated in'Figs. 4 and 5, wherethe operationv in an underneath system is indicated at the left in the gures and the ordinary trolley-controlled operation is illustrated yat the right. It will be noted that anincline isy shown at 91, down which the wheel 8| rides when it moves off the third rail, permitting the trolley to be raised by its spring to the position there shown. In order to guide the trolley so as toinsure lthat the wheel will engage the trolley wire without fail I provide a guide with` a fiat top 99 which limits the lupward movement of the wheel and with side portions |00, |0| approaching each other in the direction of movement of the car in Figs. 4 and 6, this guide being suitably supported as for example by means of a cross bar |02 and uprights |03. As the trolley moves along the guide it is forced to central position by the sides of the guide so as to engage `the wire 98 correctly and without fail.

Figs. 7, 8, and 9 illustrate a modified form of automatic trolley operating means. In this form of the invention the trolley pole. |04 is moved from the dotted line position wherein it engages the wire |05 into the position shown in solid lines, when underneath operation is indicated, by means comprising a cord or link |06 connected toa lever |01 pivoted at |08 and having pivoted thereto at its forward end a vertically movable plunger |09 .carrying a wheel ||0 at its lower end for engagement with the third rail.

It will be obvious to those skilled in the art that various changes may be made in the device of my invention, all without departing from the spirit of the invention; and therefore I do not limit myself to what is shown in the drawings and described in the specification, but only as indicated in the appended claims.

This application is a division of ymy application Ser. No. 298,104, led Oct. 5, 1939, now Patent No. 2,317,363,'April 27, 1943.
